Title:
LASER SYSTEM AND LASER MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2023/143593
Kind Code:
A1
Abstract:
A laser system and a laser measurement method. The laser system (100) comprises: a light transmitting assembly (200), which generates a transmitting signal and sequentially emits a plurality of groups of transmitted light within a current frame scanning duration according to the transmitting signal; and a receiving end assembly (400), which converts at least one group of reflected light formed by transmitted light being reflected by at least one target object (600) in a target scene (700) into an output signal. Within the current frame scanning duration, the position of a receiving field of view (102) of the receiving end assembly (400) in the target scene (700) changes according to a first specified rule and/or the shape of the receiving field of view (102) changes according to a second specified rule. Starting from a transmission start moment at which corresponding transmitted light is emitted, the transmitting field of view (101) of the light transmitting assembly (200) is located in the current receiving field of view (102) within a preset receiving duration, and the area of the receiving field of view (102) is greater than or equal to twice the area of the transmitting field of view (101). According to the described system and method, the transmitting field of view (101) and the receiving field of view (102) do not need to be accurately and synchronously matched at a high speed by using a light scanning assembly, thus the complexity and costs of the whole system can be reduced under the condition of ensuring resolution.
